INS and Insulin resistance: Parameters of insulin secretion (AUC Insulin0–30/AUC Glucose0–30, AUC C-peptide0–120/AUC Glucose0–120), proinsulin-to-insulin conversion (fasting proinsulin, fasting proinsulin/insulin, AUC Proinsulin0–120/AUCInsulin0–120) and insulin resistance (HOMA-IR, Matsuda-Index) were assessed.
